It walks through testing the alternator, then testing each battery individually with a load device, showing voltage dropping to 7 volts during startup. It ends with a battery replacement recommendation. Useful for owners with similar starting issues wanting a quick real-world diagnostic walkthrough rather than a full repair or teardown.
